A device for fine processing of optically effective surfaces on workpieces has a workpiece spindle which protrudes into a working space and by which a workpiece to be polished can be rotationally driven about a workpiece axis of rotation. Two tool spindles are associated with the workpiece spindle and protrude into the working space oppositely to the workpiece spindle. On each tool spindle, a polishing tool can be rotationally driven about a tool axis of rotation and is retained so that the polishing tool can be axially advanced along the tool axis of rotation. Furthermore, the tool spindles can be moved together in relation to the workpiece spindle along a linear axis extending substantially perpendicularly to the workpiece axis of rotation and can be pivoted about different pivoting adjustment axes, which extend substantially perpendicularly to the workpiece axis of rotation and substantially perpendicularly to the linear axis.
A device for fine processing of optically effective surfaces of, spectacle lenses as workpieces, comprising a workpiece spindle, which projects into a work space and by way of which a workpiece to be polished is drivable for rotation about a workpiece axis of rotation, and two tool spindles which are associated with the workpiece spindle and project oppositely into the work space and on each of which a respective polishing tool is mounted to be drivable for rotation about a tool axis of rotation and to be axially adjustable along the tool axis of rotation, the tool spindles being movable in common relative to the workpiece spindle along a linear axis extending substantially perpendicularly to the workpiece axis of rotation and being pivotable about different pivot setting axes extending substantially perpendicularly to the workpiece axis of rotation and substantially perpendicularly to the linear axis, wherein the tool spindles are arranged one behind the other as seen in the direction of the linear axis.
A polishing machine for simultaneous polishing of at least two spectacle lenses, comprising a machine frame in which in correspondence with the number of spectacle lenses to be simultaneously polished at least two devices are arranged, each device having a workpiece spindle, which projects into a work space and by way of which a workpiece to be polished is drivable for rotation about a workpiece axis of rotation, and two tool spindles which are associated with the workpiece spindle and project oppositely into the work space and on each of which a respective polishing tool is mounted to be drivable for rotation about a tool axis of rotation and to be axially adjustable along the tool axis of rotation, the tool spindles being movable in common relative to the workpiece spindle along a linear axis extending substantially perpendicularly to the workpiece axis of rotation and being pivotable about different pivot setting axes extending substantially perpendicularly to the workpiece axis of rotation and substantially perpendicularly to the linear axis, wherein the tool spindles are arranged one behind the other as seen in the direction of the linear axis.
